Can You Transplant A Brain Into A Young New Body? And Would You?

Posted by in categories: biotech/medical, neuroscience

Imagine that you can grow a clone with the level of intelligence below the level of a turkey or a chicken with the perfectly-exercised body. Would you consider swapping your brain with this perfect and unconscious clone? Surprisingly, many professionals would not even think twice.

Nano-robot antibodies that fight cancer enter first human drug trial

Posted by in categories: biotech/medical, nanotechnology, robotics/AI

Scientists in Israel have created the first nano-robot antibodies designed to fight cancer. The first human trial for the new nano-robots will start soon, and it will determine just how effective the antibodies are. What is special about these particular antibodies, too, is that they are programmed to decide whether cells surrounding tumors are “bad” or “good.”

The trial is currently underway in Australia and if it goes according to plan, the nano-robot antibodies will be able to fight cells around tumors that can help the tumor while also boosting the capability of the cells inhibiting the growth of the cancerous cells. The antibodies were invented by Professor Yanay Ofran and are based on human and animal antibodies.

The goal of these nano-robot antibodies is to unlock the full potential that antibodies offer, Ofran says. Currently, the use of antibodies in medicine only utilizes a fraction of the capabilities offered by these natural disease fighters. As such, finding a way to maximize their capability has been a long-term goal for quite a while.

Genome studies uncover a new branch in fungal evolution

Posted by in categories: biotech/medical, evolution

About 600 seemingly disparate fungi that never quite found a fit along the fungal family tree have been shown to have a common ancestor, according to a University of Alberta-led research team that used genome sequencing to give these peculiar creatures their own classification home.

“They don’t have any particular feature that you can see with the where you can say they belong to the same group. But when you go to the , suddenly this emerges,” says Toby Spribille, principal investigator on the project and associate professor in the Department of Biological Sciences.

“I like to think of these as the platypus and echidna of the fungal world.”

Personality similarity predicts synchronous neural responses in fMRI and EEG data

Posted by in category: neuroscience

Successful communication and cooperation among different members of society depends, in part, on a consistent understanding of the physical and social world. What drives this alignment in perspectives? We present evidence from two neuroimaging studies using functional magnetic resonance imaging (fMRI; N = 66 with 2,145 dyadic comparisons) and electroencephalography (EEG; N = 225 with 25,200 dyadic comparisons) to show that: the extent to which people’s neural responses are synchronized when viewing naturalistic stimuli is related to their personality profiles, and that this effect is stronger than that of similarity in gender, ethnicity and political affiliation.

Highly ruminative individuals with depression exhibit abnormalities in the neural processing of gastric interoception

Posted by in categories: biotech/medical, neuroscience

Major depressive disorder is associated with altered interoception — or the ability to sense the internal state of your body. Now, new brain imaging research provides evidence that depressed individuals tend to exhibit “faulty” neural processing of gastric interoception, particularly among those with high levels of rumination. The findings have been published in the Journal of Psychiatric Research.

“Repetitive negative thinking (RNT), usually referred to as ‘rumination’ in persons who suffer from depression, is a very significant clinical problem,” explained study author Salvador M. Guinjoan, a principal investigator at the Laureate Institute for Brain Research and associate professor at Oklahoma University Health Sciences Center at Tulsa.

“The reason is that when it is severe and persistent, RNT conditions higher chances of depression relapse and is associated with residual symptoms after treatment, is more common in persons who do not respond to treatment, and is even related to suicide. This particular communication refers to one among a series of projects in our lab attempting to understand rumination.”

Physiological responses to playing Overwatch depend on skill level, study finds

Posted by in categories: entertainment, health

A study of physiological responses of college-age Overwatch players found that many skilled players tend to start the game with elevated physiological stress responses, adjusting them during gameplay. The physiological stress responses of low skill players, in contrast, tend to increase as the game progresses. The study was published in the Journal of Strength and Conditioning Research.

Competitive electronic gaming or eSport is gaining traction as a recognized sport. The rise of eSports into a multi-billion dollar industry has been attributed to the emergence of streaming platforms and advertisement revenues and high-values sponsorships that came with them. eSports are one of the 24 competitive sports included in the 2022 Asian games held in Hangzhou, China.

Following their rise in popularity, scientists have become interested in studying eSports athletes to understand the stress related to participating in eSports both in competitive and noncompetitive settings. First studies focused on health concerns, given the sedentary nature of eSports, and primarily studied players of League of Legends (LOL) as one of the most popular eSports games at the time.

Water wars: Causes and possible solutions

Posted by in categories: economics, food

Will today’s wars over oil be over water in the future? For years this question has been at the heart of a scientific debate on the causes of these wars and how they should be studied.

A study published in the prestigious Nature Sustainability by a group of researchers from the Politecnico di Milano has investigated the phenomenon, also in light of “new” types of in which paramilitary groups seem to capitalize on .

In order to define the relationship between water and conflict, speaking only of —or lack thereof—is not enough: in fact, conflicts tend to be associated with specific and complex socio-hydrological conditions, which in turn deal with the socio-economic value of water as a form of livelihood, especially in agriculture, and with the effects that human use of water has on the accessibility of this resource.

Transporting of two-photon quantum states of light through a phase-separated Anderson localization optical fiber

Posted by in categories: particle physics, quantum physics

Invented in 1970 by Corning Incorporated, low-loss optical fiber became the best means to efficiently transport information from one place to another over long distances without loss of information. The most common way of data transmission nowadays is through conventional optical fibers—one single core channel transmits the information. However, with the exponential increase of data generation, these systems are reaching information-carrying capacity limits.

Thus, research now focuses on finding new ways to utilize the full potential of fibers by examining their and applying new approaches to signal generation and transmission. Moreover, applications in are enabled by extending this research from classical to .

In the late 50s, the physicist Philip W. Anderson (who also made important contributions to particle physics and superconductivity) predicted what is now called Anderson localization. For this discovery, he received the 1977 Nobel Prize in Physics. Anderson showed theoretically under which conditions an electron in a disordered system can either move freely through the system as a whole, or be tied to a specific position as a “localized electron.” This disordered system can for example be a semiconductor with impurities.
